The Saudi embassy in Washington, D.C. today denied its government warned the U.S. about accused Boston bomber Tamerlan Tsarnaev.

According to a highly placed source who spoke to MailOnline, the Saudis sent a written warning about Tsarnaev to the U.S. Department of Homeland Security in 2012. That was long before pressure-cooker blasts killed three and injured hundreds.

The official told MailOnline about a written warning from the Saudi government to the Department of Homeland Security, and said he had direct knowledge of that document.

But the Middle Eastern nation’s embassy in Washington denied that account on Wednesday.

It issued a statement which read: ‘The Saudi government had no prior information about the Boston bombers. Therefore, it is not true that any information, written or otherwise, was passed to the U.S. Department of Homeland Security (DHS) or any other US agency in this regard,’ an embassy statement statement claimed.

‘The Saudi government also does not have any record of any application by Tamerlan Tsarnaev for any visa to Saudi Arabia.’
